Import showing all photos on One Drive Camera Roll as NEW photos

I let it churn for only a few minutes yesterday, but will let it run this evening.  I noticed when it stops churning/spinning, I just need scroll down a bit to start the next churn.

Yes, photos are in the cloud in OneDrive.  LrC is looking at folder c:\users\myname\cloud\onedrive\pictures\camera roll at import.  I always select New Photos and Move when importing, so typically the remaining number of photos in the Camera Roll tends to be small or at least manageable.  Somehow, my once depleted Camera Roll was filled back up with every photo since early 2019. 

So I think this happened after upgrading to v12.0, but I don't rememer if it was right after because the other wrinkle related to OneDrive is I also switched to a new phone over the weekend (minor upgrade from Samsung to Samsung using their SmartSwitch app).  I would have signed into the OneDrive app on the new phone, but don't recall messing with any of the app settings.  Just sat down at my pc a few days ago and OneDrive was downloading the 10,000+ files.  

Lightroom is now also very slow.  Takes around 60 seconds from when I open Import Photos & Videos to when the thumbnails start appearing.

And perhaps LrC reading info on those images, then comparing with what is in the catalog is taking even longer. How long did you let LrC churn on that before leaving import? 

When I go to Import Photos & Videos the same way I have for years, Lightroom Classic is now showing all 10,000+ photos from my One Drive Camera Roll

So the images are on a cloud share, or network share. LrC does not do well when a network or for that matter cloud share is involved. Absolutely not supported for the catalog, but can also be problematic for the original photos. Oh, it can work, but not nessecarily forever.

So, a member with experiance in One Drive???

Inquiry, was this occuring when you first upgraded to v12.0?
